Hi there,

One of our staff upgraded something (I don't know what was it, the theme or the plugin), after that this error appears:

Uncaught Error: Call to undefined function TheGem_ElementorWidgetsPortfolioget_thegem_portfolio_render_item_classes() in /home/bnigreece/public_html/wp-content/plugins/thegem-elements-elementor/inc/elementor/widgets/portfolio-grid1/widget.php:2905 Stack trace: #0 /home/bnigreece/public_html/wp-content/plugins/elementor/includes/base/controls-stack.php(2192): TheGem_ElementorWidgetsPortfolioTheGem_Portfolio->render() #1 /home/bnigreece/public_html/wp-content/plugins/elementor/includes/base/widget-base.php(584): ElementorControls_Stack->render_by_mode() #2 /home/bnigreece/public_html/wp-content/plugins/elementor/includes/base/widget-base.php(725): ElementorWidget_Base->render_content() #3 /home/bnigreece/public_html/wp-content/plugins/elementor/includes/base/element-base.php(447): ElementorWidget_Base->print_content() #4 /home/bnigreece/public_html/wp-content/plugins/elementor/includes/base/element-base.php(741): ElementorElement_Base->print_element() #5 /home/bnigreece/public_html/wp-content/plugins/ in /home/bnigreece/public_html/wp-content/plugins/thegem-elements-elementor/inc/elementor/widgets/portfolio-grid1/widget.php on line 2905


It seems like two functions are not defined (maybe you forgot to include theme)?

I asked the boss, he said no. Please don't update it. The developer who worked on theme, didn't add a child theme. So this mess came up.

Do you have any suggestion? Is there any way we could handle it without updating? 

I have a backup from files (not database for now).

I will try to install this backup on some other server and then I will update the theme and let you know what happens.
